Inter- and intraspecific genetic and morphological variation in a sibling pair of carabid species.

ABSTRACT: BACKGROUND:Pogonus littoralis and Pogonus chalceus are very close related species with quite different ecological preferences within salt marshes. We study the evolutionary processes in and between these presumably young species. Therefore, we compare the variation in ecologically relevant characters and the genetic variation within one of the species (intraspecific differentiation) with the variation of the two types of characters between the two species (interspecific variation). Data are compared between two independent sets of populations, one set at a small geographical scale (the ecologically diverse Guérande area in France) and the other set at a Atlantic-Mediterranean scale. RESULTS:Body and relative wing size and IDH1 allozyme data show that the intraspecific variation in P. chalc
